I have 2 of these. I take it you're after the individual on/off switches.

Yeah, that's the one

I went to Long & McQuade.
They no longer stock or carry the 8 outlet American DJ powerbars (recently discontinued).

However they do stock a 4 outlet powerbar by American DJ (it was not on their website when I checked), I ordered 2 of them, cost was approx $30 each.
